b90.X Digital input X status
. If X is greater than 7, parameter with save facility at user’s
disposal (b90.0 = drive enable).
b91.Y Digital input Y status
. If Y is greater than 7, parameter with save facility at user’s
disposal. Parameter Pb91 is not saved at power up and is definitely at zero.
Pr92
First PLC timer
. Every 6.144 ms if Pr92 is not at 0 the timer is decreased, if set to
zero b99.0 is set at 1.

If Pr60..Pr68 are utilised, double word formatting is automatic (see text).
b94.5
Disables the first fast input
(b94.5=0). Set to zero at power-up.
b94.6
Disables the second fast input
(b94.6=0). Set to zero at power-up.
b94.7
Disables the third fast input
(b94.7=0). Set to zero at power-up.
b99.0
First timer status.
At 1 if Pr92 = 0
b99.1
Second timer status.
At 1 if Pr93 = 0

At 1 if the result of the last PLC operation is negative.
b99.3
At 1 if the result of the last PLC operation is zero.
b99.13 PLC status
